LEPDICT addresses the topic of light-emitting diodes (LED), one of Europe's Key Enabling Technologies of the 21st Century, and combines efforts and knowledge from organic and polymer chemistry, materials science, physics and engineering.

​

LEPDICT is primarily about developing and validating new approaches, generating new, basic and applied, transferable knowledge, and further pushing the boundaries of its contemporary research topics. The main research strategy is based on the dynamic chemical engineering of materials with a main focus on modulating light-emitting polymeric backbones to balance charge transport through (chromophoric) p-n systems.

​

The foremost chemical concept is the construction of luminescent polymeric systems containing various moieties able to emit light of different colors. LEPDICT's goal was to find the optimal combination of active structural elements in the same macromolecular architecture to develop materials capable of acting as active layers in LEDs with minimal efficiency. 

​

LEPDICT was placed at a TRL 2 value at its beginning and designed to reach a TRL 4 end value through the engineering, optimization and validation of PLED prototypes by following various performance targets.

​

Several series of materials (organic compounds, polymers, mixtures, and hybrid materials) with a specific optical response (light emission of a certain color) have been designed, tested, and validated in blue and white light emitting (lab scale) PLED prototypes meeting a rigorous set of performance targets.

​

The new guidelines in materials’ design and fabrication of LED devices and the enrichment of the available range of materials for the topic provide reliable solutions (with an optimal cost/performance ratio compared to other approaches) to key problems in the field.
